C
– Relay configuration DIP switches
The DIP switches allow to choose between normally energized relay (the coil
is energized when not in alarm) or normally de-energized relay (the coil is
energized when in alarm). Set the switch to ON for energized relay or OFF for
de-energized relay. Each switch drives the relay having the same number
(switch #1 acts on relay #1). The contacts are represented with the module
not powered.
Re the 4 relay module, only switches #1 to #4 are active.
2 logic inputs
4 or 8 output relays
4 wire serial cable
